A four-wheel drive vehicle has a front solid drive axle suspension and a rear solid drive axle suspension. The vehicle has a CG height of 20.5 in, a wheelbase of 108.5 in, and tires of 15 in radius. Also, 60% of this vehicle's total drive force is developed on the front axle, and 55% of this vehicle's brake force is developed on the front axle. i) Determine ratios of e/d¡ and e./d; that will provide 100% anti-dive during braking. ii) Given your answers to Part i) find a ratio of K/Kr that will result in a zero pitch rate during driving (i.e. positive acceleration).

A four-wheel drive vehicle has a front solid drive axle suspension and a rear solid drive
axle suspension. The vehicle has a CG height of 20.5 in, a wheelbase of 108.5 in, and tires
of 15 in radius. Also, 60% of this vehicle's total drive force is developed on the front axle,
and 55% of this vehicle's brake force is developed on the front axle.

i)
Determine ratios of e/df and e,/d; that will provide 100% anti-dive during braking.
Given your answers to Part i) find a ratio of Kf/Kr that will result in a zero pitch
rate during driving (i.e. positive acceleration).
